摘要： A groove processing device, which processes a cylinder groove to an inner circumference of a cylinder to protrude from an inner circumferential surface toward an outer circumferential surface side and extend in a center line direction of the cylinder, includes: a first groove processing unit that process both end portions of the cylinder groove in a circumferential direction thereof, and a second groove processing unit that processes a center portion of the cylinder groove in the circumferential direction thereof, wherein an outermost circumferential portion of each of the first groove processing unit and the second groove processing unit being formed to be a chevron shape so that a center portion thereof in the circumferential direction of the cylinder protrudes, and an inclination angle from a vertex portion in the outermost circumferential portion of the first groove processing unit is larger than that of the second groove processing unit.

摘要： In a tube expanding apparatus of a damper tube supporting a thrust force of a punch applied to the damper tube by a stopper at a time of retaining one end of the damper tube by the stopper, inserting the other end of the damper tube to a die, inserting the punch to the other end of the damper tube so as to propel, and expand the other end of the damper tube while carrying out an ironing operation, the apparatus is provided with a stopper releasing means for releasing the stopper at a time when a load in an axial direction applied to the damper tube due to an elongation by the ironing work of the damper tube increases over a critical load which is previously determined to be a smaller load than an expected buckling load in the damper tube.
摘要翻译： 在阻尼管的管膨胀装置中，通过止动件将阻尼管的一端固定在阻尼器的一端上时，通过塞子支撑施加到阻尼管的冲头的推力，将阻尼管的另一端插入模具 将冲头插入阻尼管的另一端，以便在进行熨烫操作的同时推进并扩张阻尼管的另一端，该装置设置有止动器释放装置，用于在制动器的时候释放塞子 由于缓冲管的熨烫工作的延伸而施加到阻尼管的轴向负载在先前确定为比减震管中的预期屈曲载荷小的负载的临界负载下增加。
